Head drum for magnetic tape device has multipart transformer that transfers signal between two head drum parts, magnetic liquid between movable and stationary parts of transformer

摘要

The head drum has a stationary part (K1) and a moving part (K2), on which is mounted a head (H1, H2) for reading from and/or writing to a tape. A multipart transformer (TR1, TR2) transfers a signal between the two parts of the head drum. A magnetic liquid (M) is arranged between a movable and a stationary part of the transformer. Independent claims are also included for a magnetic tape device and for a magnetic liquid.
